DAMASK JACQUARD LOOM.

SPECIFICATION forming part of Letters Patent No. 786,389, dated April 4,1905.

Application filed February 27, 1903. Serial No. 145,313.

To all 1071 0711, it many concern:

Be it known that I, FRrrz AUeUsTINUs STER- NER, master weaver, a subjectof the King of Sweden and Norway, and a resident of Abe, Finland,Russia, have invented certain new and useful Improvements in DamaskJacquard Looms; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

As above stated, this invention relates to a mechanical damask Jacquardlo'om in which the same saving of pattern-cards, patterndrawings, andwork which is won by the execution of ordinary damask-weaving by handcan be effected without the employment of so-ealled forward healds orother extra means of assistance. Besides this the production of analmost unlimited number of large patterns is rendered possible.

This invention is principally intended to effeet the binding in ajacquard-pattern in such manner that the number of rows of liftingwiresis made dividable with the number of bindings in the binding and thatthis binding is accomplished by means of entire rows of lifting-wires inthe order as indicated by the binding being compelled to remain downwardand other entire rows of lifting-wires in the same order being compelledto rise, independent of which special wires have been receded or not.

In a form of the machinenamely, the one shown in Figures 1 to 5- theordinary needles and the ordinary pattern-card prisms, as well asbinding-disks, are present. Fig. 1 shows an end view of. thefirstmentioned form, Fig. 2 a front view, and Fig. 3 shows the devicefor turning the pattern-card prism. Fig. 4 shows the arrangement of thewires or hooks, the needles, and so-called binding-disks, and Fig. 5shows the arrangement for maneuvering the binding-disks. Fig. 6 shows apreferred form of the apparatus in which the binding is effected bymeans of a cam-cylinder in place of the binding-disks.

The machine consists of a frame at the opposite ends of which thehorizontal shafts b ed upon.

are fitted, to which shafts are imparted simultaneous motion by means ofa shaft and conical cog-wheel c, mounted onto the side of the frame.Themaehine can be fitted to anyloom and is set in motion by means of theshafts b, which by means of a shaft s and cog-gear (r are placed incommunication with one of the shafts of the loom. On the shafts b aremounted eccentrics (Z, which move in grooves fitted in vertical-movingraisers or lifting-blades c, with whose upper ends the lifting-plates Tare firmly lixed. On both sides of the raisers racks q are fitted, andin these one of the ends of the double-armed levers f engages, whichlevers are provided with cog-segments. The other ends engage racksarranged at the board 1 under the lifting-wires, which by this means islowered when the lifting-plates'l,

with the lifting-blades t, are raised, and vice versa.

The card-prism l is horizontally and pivotally mounted on bars 2 fittedto the frame, and on its bearings taps 2 are fitted, which enter thegrooves of grooved or worm Wheel 7:, fitted on shafts i, whichworm-wheel in its rotation sets the card-prism in motion to and from theneedles 1' and by means of taps in, attached to the said worm-wheel,which taps come into contact with taps w, fitted on the prism, turn theprism when it occupies a position farthest from the needles. The prismis kept in position by means of spring-actuated taps 1, which engagewith their plane ends one of the sides of the prism, thus keeping itsteady, but yet, by reason of springpressure when the tops m are actedupon, allow its being turned round. The shafts 1' are connected with theshafts b by means of coggear it and are set in motion by them.

The binding in the pattern is effected by horizontal binding-blades p,which are fitted at the ends of the machine. The bearing-taps of theblades 1) are fitted close to the upper edges of the'latter, by means ofwhich the blades hang vertically when they are not act- One of the tapsof each of these blades is constructed in the form of a crank, by meansof which the blades can be turned by projections to on rollers 0, fittedon asha'lt 2, which by means of chain-gearing 77' is connected with theshafts The needles and wires are arranged in the ordinary way.

In order to clearly explain the functions of the machine, an example ofits method of working is here shown adjusted for a certion product. Thecog-wheels in the gear it are so adjusted that worm-wheels 71; make onerevolution in the same time as the shafts 1) make as many revolutions asthreads desired in a socalled web unit, (in this instance three.) Afterthe third revolution the card-prism, which in the meantime has beenpressed against the needles, is carried by the worm-wheel 72 away fromthe needles and is turned simultaneously by the taps 411, so that a newcard is turned toward the needles. (See Figs. 3 and 4.) Every needle isconnected with as many wires as threads desired in a so-called web-unit,(in this case three.) Suppose that five-binding satin is to bemanufacturedzi. e. similar binding shall be effected at every fifth weftthen it must be so arranged that the shaft 2 makes one revolution whilethe shafts 5 make as many revolutions as indicated by the number ofbindings, (in this instance five,) whereby the rows of lifting-wires, asnumbered in Fig. 4, are acted upon by the binding-disks, of which oneisarranged between each row of lifting-wires in the following order: Atthe first weft the first, sixth, eleventh, and so on, binding-disks areturned and convey thereby every fifth row of lifting-wires back onto thelifting-blades, if so-called light satin is to be manufactured 0.,first, sixth, eleventh, and so on, and every fifth row from these e.second, seventh, twelfth,&c.; but if heavy satin is to be manufacturedthe disks turn the first, sixth, and eleventh, &c., rows from thelifting-blades, and the second, seventh, and twelfth, 620., rows towardthe lifting-blades. At the second weft in the first instance the third,eighth, thirteenth, &c., rows of lifting Wires or hooks forward, and thefourth, ninth, fourteenth, &c., back, but in the latter case vice versa.At the third weft the fifth, tenth,

fifteenth, &c. rows of lifting-wires are carried forward, and so on. Thewires are conveyed,

as known, downward by their own individual weight and rest with theirlower ends against the board under the lifting-wires g, resting withtheir upper ends against the lifting-blades t, providing they are notmoved from the blades by the needles. In accordance with Fig. 6 thereare no binding-disks, but the binding is here effected by the assistanceof a prism 3, provided with grooves 5 on its periphery, and in thesegrooves entering taps 9, which are fitted on the lifting-blades 6 andconvey these latter to and from the binding wires or hooks 12, so thatcertain ones of these may be acted upon by the blades as they (theblades) ascend. 11 is the lifting-plate, which also supports thecylinder 3. This so-called binding-cylinder is now given a rotarymovement by a pawl or hook 10, (which is fitted in the frame of themachine and at the downward movement of the lifting-plate IL and thecylinder 3 acts upon a cog-wheel 4, connected with the cylinder,)whereby every tooth on the cog-wheel, respectively every projection atthe side of the grooves 5 in the periphery of the cylinder correspondsto a new weft-stroke. in order to prevent the cylinder turning ofitself, a spring 7 may rest against the cog-wheel 4.

Having thus described my invention, what I claim, and desire to secureby Letters Pat- In a damask Jacquard loom, provided with as many hooksor wires to every needle as it is desired to have threads to a warpunit, the combination of rotatable lifting-blades 6, between said hooks,said blades being provided with taps 9, a cylinder or other rotatingelement 3 provided with grooves 5 with which said taps engage in orderto cause the lift-ingblades to engage the hooks and to operate them in agiven order, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
